/defaults option not working on command line

/defaults option not working on command line

when entering /defaults at end of command line winscp scp string get weird windows dialog error message about including URL and after clicking that off session runs but dialog to copy appears anyway as if in gui session.. Other than that the command line for scp with multiple files works..

with popup dialog though would not be able to run via windows scheduler of course which is main problem..

while running command line parameters, the upload works fine. (unable to use /defaults though)
But when i try to use scripting/commands as "open user:pass@ip" it reads "open user" as the session name and throws an error. Am i missing something trivial here
